Abstract: In this direction, in the present study an effort has been carried out to optimize the section based on the bending moment diagram and made tapered to obtain a suitable utility for a most critical load combination as per IS 800:2007 [table 4]. The conventional structure is costly due to uniform steel sections throughout the member length. In contrast, the tapered section reduces steel consumption by a certain amount. In this study, an optimization of industrial sheds of different spans and geometries is carried out. The load calculations are carried out as per IS 875 parts 1, 2 and 3. The design checks are performed as p er Indian Standard Code IS 800:2007 (LSM). The analysis and design have been carried out using the staad-pro software. The main goal of the study is to achieve the cost-effective frame based on changes in geometry, width, and angle of roof in terms of weight, as well as to investigate the variation in results.

Keywords: Industrial shed, tapered section, hot-rolled section, monoslope roof, pitched roof, butterfly roof.
